Rainwater Harvesting

Driven by Building Regulations, The Code for Sustainable Homes and BREEAM the need to improve water management, reduce dependency on mains water and increase water supply to areas of water scarcity all mean that rainwater harvesting is the logical solution. It also has the potential to reduce the volume of water wastage and save money on water bills. In domestic applications savings of up to 50% can be achieved and up to 85% can be saved within commercial applications.
Rainwater harvesting is the collection, filtering and storing of rainwater from the roofs of buildings.

What is Rainwater Harvesting?

Rainwater Harvesting works by taking the rain from your roof gutters, filtering out leaves and debris and storing the water in an above ground or underground tank. This water can then be used for non-potable applications such as vehicle washing, irrigation, toilet flushing and washing machines. A KingspanWater expert will be able to guide you to the appropriate rainwater harvesting system for your application.
